Thunderchord's Blessing

You or a creature you choose becomes able to hear the rhythm of the storm inside themselves.
For the duration of the spell, the caster can bestow you with two of the following effects:

Storm Imbued
Your weapons crackle with blue-violet sparks and deal an additional 1d6 lightning damage on hit.

Shock and Awe
A raincloud hovers 30ft above you in a 20ft radius. You can summon a small lightning bolt at a place of your choosing within that area as an action, dealing 3d6 lightning damage and blinding your target for 1 unless they succeed on a dexterity saving throw against the caster's spell save DC. Recharge 5-6.

Flashing Footwork
Your walking speed increases by 10ft and you can take the dash action as a bonus action if you damage an enemy with an attack in the same turn. You are immune to the prone condition.

Thunderous Retribution
When you take damage, you can use a reaction to let out a roar of thunder from yourself in a 10ft radius, pushing all creatures of medium (medium, huge) or smaller size back out of the radius and dealing 2d4 damage unless they succeed on a strength saving throw against the caster's spell save DC.

Living Lightning (5th level and up)
Your attacks, spells and abilities that deal lightning damage ignore resistance.

Whilst under the effects of this spell, if you fail to attack during your turn you must succeed on a constitution saving throw (DC 13), or take 2d6 lightning damage as the storm inside you becomes uncontrolled, ending the spell early. When casting this spell with a spell slot above level 3, you can choose one more effect for each level above 3rd of the spell slot used.
